       4. The method of  claim 1 , wherein the change in distance between the user of the electronic device and the electronic device is a change in distance between the electronic device and eyes of the user, and the method includes changing size of the displayed user interface object by an amount that is based on the change in distance between the electronic device and the eyes of the user. 
     
     
       5. The method of  claim 1 , wherein changing size of the displayed user interface object includes changing a zoom factor based on rotation of the electronic device. 
     
     
       6. The method of  claim 5 , wherein rotation of the electronic device is determined, using the camera, based on orientation of the electronic device in relation to the user. 
     
     
       7. The method of  claim 1 , including changing a zoom factor for the user interface or user interface object based on a tilting of the device, wherein tilting the device in a first predefined direction increases the zoom factor and tilting the device in a second predefined direction decreases the zoom factor. 
     
     
       8. The method of  claim 7 , wherein tilt of the electronic device is determined, using the camera, based on orientation of the electronic device in relation to the user. 
     
     
       9. An electronic device, comprising:
 a processor; 
 a camera; and 
 a display in communication with the processor, wherein the processor is configured to:
 display, on the display, a user interface that includes a user interface object displayed at a first size; 
 detect, via the camera, a change in distance between a user of the electronic device and the electronic device; and 
 in response to detecting the change in distance between the user of the electronic device and the electronic device, change size of the displayed user interface object. 
 
 
     
     
       10. The electronic device of  claim 9 , wherein the processor is configured to, in response to detecting the change in distance between the user of the electronic device and the electronic device, change size of the displayed user interface object in accordance with the change in distance between the user of the electronic device and the electronic device. 
     
     
       11. The electronic device of  claim 9 , wherein the processor is configured to set a zoom mode of the device to enable zooming, and changing size of the displayed user interface object comprises zooming in on a portion of the user interface. 
     
     
       12. The electronic device of  claim 9 , wherein the change in distance between the user of the electronic device and the electronic device is a change in distance between the electronic device and eyes of the user, and the processor is configured to change size of the displayed user interface object by an amount that is based on the change in distance between the electronic device and the eyes of the user. 
     
     
       13. The electronic device of  claim 9 , wherein changing size of the displayed user interface object includes changing a zoom factor based on rotation of the electronic device. 
     
     
       14. The electronic device of  claim 13 , wherein rotation of the electronic device is determined, using the camera, based on orientation of the electronic device in relation to the user. 
     
     
       15. The electronic device of  claim 9 , wherein the processor is configured to change a zoom factor for the user interface or user interface object based on a tilting of the device, wherein tilting the device in a first predefined direction increases the zoom factor and tilting the device in a second predefined direction decreases the zoom factor. 
     
     
       16. The electronic device of  claim 15 , wherein tilt of the electronic device is determined, using the camera, based on orientation of the electronic device in relation to the user. 
     
     
       17. A non-transitory computer readable storage medium, storing one or more programs, which when executed by one or more processors of an electronic device having a display and a camera, cause the electronic device to perform operations comprising:
